Apparatus and method to seal a tissue tract

A device for depositing a material, optionally a sealant, within a tissue, the device comprising:

• a housing comprising a housing proximal end, a housing sheath, and a housing distal end;
• and,
• a tissue introducer positioned within the housing sheath and comprising a tissue introducer sheath, a tissue introducer proximal end, and a tissue introducer distal end comprising a distal port;
• wherein:
• where the tissue introducer is positioned within the housing sheath the tissue introducer and housing sheath form a coaxial configuration and the tissue introducer distal port is located distal to the distal end of the housing sheath;
• and,
• the housing comprises a seal configured to prevent the flow of air, gases, or fluids from entering or exiting the housing sheath therein;
• the tissue introducer comprises a sealant reservoir attached to the proximal end that is in fluid communication with the distal port;
• where the tissue introducer is positioned within the housing sheath, the housing sheath surrounds the tissue introducer;
• and,
• the tissue introducer comprises a beveled distal tip configured to pierce through tissue.

A method of depositing a material, optionally a sealant, within a tissue, the method comprising:

• inserting a device into the tissue towards a target;
• applying a sealant material to the tissue from the device to the lung parenchyma located internal to the visceral pleura;
• advancing the device into the tissue after applying the sealant to the target tissue;
• and, performing a treatment on the target tissue.
